Description

Technical Field

[0001] This utility model belongs to the field of rice seedling technology, specifically relating to a rice seedling sower. Background Technology

[0002] A rice seedling planter is a mechanical device used for rice cultivation that automates the sowing and seedling raising process. When using a rice seedling planter, the prepared nutrient slurry is first spread on the seedling trays, and then the machine evenly sows the seeds into the slurry. The machine can monitor the sowing process in real time through an intelligent monitoring system, ensuring precise control of the sowing rate per acre and preventing double sowing and missed sowing. This machine is suitable for large-scale rice cultivation, and performs particularly well in scenarios requiring efficient and uniform sowing. Existing rice seedling planters mainly consist of a nutrient mud storage bucket, a seed storage bucket, a water bucket, a laying device, seedling trays, and a conveyor belt. The seedling trays are gradually fed into each stage of the process via the conveyor belt until the seeds are sown on the trays. At this point, workers remove the sown seedling trays, stack them onto a trolley, and then transport them to a greenhouse or seedling room for seedling cultivation. After the seedlings germinate, they are laid in the field or transplanted by a rice transplanter. However, the repeated process of removing, stacking, and transporting the sown seedling trays from the conveyor belt is cumbersome. Specifically, workers must hold each sown seedling tray individually and transport them to a support plate for stacking, which is inconvenient in operation. Utility Model Content

[0003] This utility model discloses a rice seedling planter, which aims to solve the above-mentioned technical problem of the inconvenience of manually stacking the seedling trays after sowing.

[0004] To solve the aforementioned technical problems, the present invention adopts the following technical solution: A rice seedling planter includes a planter body with a conveying section. The conveying section is connected to a stacking device. The stacking device includes a guide device that contacts the conveying section. The guide device is connected to a stacking box that cooperates with seedling trays. A stacking tray is slidably mounted on the stacking box. A telescopic device is provided between the stacking box and the stacking tray. The stacking tray can be quantitatively extended or retracted according to the number of seedling trays, so that the top of the seedling trays already stacked on the stacking tray is always parallel to the guide surface of the guide device.

[0005] With this technical solution, the seedling trays complete a series of actions such as spreading soil and sowing seeds on the conveying unit. One end of the conveying unit is first connected to a guiding device, and then to a stacking box. Initially, the guiding surface of the guiding device, the conveying surface of the conveying unit, and the top surface of the stacking tray are parallel. That is, the seedling trays can first enter the guiding device under the pushing action of the conveying unit. Subsequent seedling trays can push the seedling trays entering the guiding device, so that the seedling trays on the guiding trays come into contact with the stacking trays in the stacking box, and gradually slide onto the stacking trays and be supported by the stacking trays. This continues until a stacking box is full of stacked seedling trays. During the process of supporting the seedling trays, the telescopic device can adaptively extend and retract according to the number of seedling trays. The specific extension and retraction height is the number of seedling trays multiplied by the height of the seedling trays. This ensures that the top of each new seedling tray is parallel to the guiding surface of the guiding device and the conveying surface of the conveying unit, facilitating the support of the next seedling tray to be stacked on the stacking tray. In this way, all the seedling trays can be stacked on top of each other in the stacking tray and stacking box. After the corresponding number of seedling trays are stacked in a stacking box, the user can take out the entire stacked seedling trays from the opening on the stacking box. This reduces the difficulty for users in stacking seedling trays that have already been sown, simplifies the stacking operation of seedling trays, and increases the user's comfort when using this device.

[0006] The palletizing tray is detachably connected to the telescopic device, which is a telescopic rod and has an elastic device inside. The palletizing box has an opening for removing the already stacked seedling trays, and the opening is located on the side of the palletizing box away from the guide device.

[0007] After adopting this technical solution, the seedling trays that need to be stacked enter the stacking box from the guide device and move out from the opening. The opening is set on the side away from the guide device. This setting makes the movement of the seedling trays reasonable, and the operation process of stacking and taking out the stacked seedling trays is relatively smooth and undisturbed.

[0008] The detachable connection between the palletizing tray and the telescopic device allows the entire box of seedling trays to be removed along with the palletizing tray after one box of seedling trays has been stacked. Then, a new palletizing tray can be installed to start stacking a new box of seedling trays, thus improving the efficiency of seedling tray stacking.

[0009] The elastic device allows the telescopic rod to automatically return to its original position when the stacked seedling trays are removed, making it easy to install new stacking trays and providing greater convenience in use.

[0010] The telescopic rod has a first insert block at its top, and the palletizing tray has a first slot at its bottom that mates with the first insert block.

[0011] By adopting this technical solution, the setting of the first insert and the first slot simplifies the connection between the palletizing tray and the telescopic rod, and improves the efficiency of the connection between the palletizing tray and the telescopic rod.

[0012] The conveying unit includes a conveyor belt with first baffles at both ends. One end of the guiding device is connected to the first baffles, so that the guiding device contacts the end of the conveyor belt, and the other end of the guiding device is connected to the palletizing box.

[0013] With this technical solution, one end of the guiding device is connected to the first baffle, and the other end is connected to the palletizing box, allowing the guiding device to connect with the conveyor belt without affecting its use. Simultaneously, it ensures that the conveying surface of the conveyor belt, the guiding surface of the guiding device, and the top surface of the palletizing device or the top surface of the palletizing tray are parallel, facilitating the stacking of seedling trays and improving the stability of the seedling trays running on the guiding device and the palletizing box or on already stacked seedling trays.

[0014] The guiding device includes two guide rails, with a second baffle on the top of each guide rail. The palletizing tray has two symmetrical third baffles, which are located in the extension direction of the second baffles. A limiting groove for limiting the position of the seedling tray is formed between the two second baffles and the third baffles.

[0015] By adopting this technical solution, the design of the guide rail simplifies the structure of the guiding device, reduces the amount of material used in the guiding device, and thus reduces the cost of setting up and using the guiding device.

[0016] The setting of the first baffle, the second baffle, the third baffle, and the limiting groove can limit the seedling trays during transportation, making the seedling trays more stable during transport and stacking, improving the stability of the device during use, and thus improving the effect of transporting and stacking seedling trays.

[0017] The guide rail is provided with several rollers, and the rollers are disposed between two guide rails.

[0018] By adopting this technical solution, the roller configuration improves the smoothness of seedling tray transportation on the guide rail and enhances the user's comfort when stacking seedling trays using this device.

[0019] The palletizing box has a U-shaped structure and includes a base plate and two side plates vertically arranged on the base plate. The two side plates are symmetrically arranged and are located on the extension line of the guide device.

[0020] After adopting this technical solution, the U-shaped palletizing box not only facilitates the stacking of seedling trays and the removal and transportation of the stacked seedling trays, but also reduces the number of side walls of the palletizing box, reduces material usage, and lowers costs.

[0021] In summary, due to the adoption of the above technical solution, the beneficial effects of this utility model are:

[0022] (1) Using guiding devices, stacking boxes, stacking trays, etc., seedling trays that have been sown can be stacked without the need for manual stacking of each seedling tray, which is more convenient to use.

[0023] (2) The use of telescopic rods, elastic devices, etc., has improved the rate of pallet replacement, thereby ensuring the rate of seedling pallet stacking.

[0024] (3) The use of guide rails and the like can simplify the structure of this device, reduce the amount of materials used in this device, and thus reduce costs.

[0025] (4) The use of second baffles, third baffles, etc. ensures the stability of seedling trays during transportation and stacking, and improves the stability of the device during use.

[0026] (5) The use of rollers and other equipment increases the smoothness of seedling trays during transportation and stacking, thus making the device more efficient to use. Attached Figure Description

They are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this application. In addition, the terms "first," "second," and "third," etc., are only used to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0032] The following is combined Figs. 1-2 This utility model will be described in detail.

[0033] A rice seedling planter, such as Figs. 1-2 As shown, the seeder body includes a conveying section, which is connected to a stacking device. The stacking device includes a guide device that contacts the conveying section. The guide device is connected to a stacking box 7 that cooperates with the seedling trays 3. The stacking box 7 is slidably connected to a stacking tray 6, and a telescopic device is provided between the stacking box 7 and the stacking tray 6. The stacking tray 6 can be quantitatively extended and retracted according to the number of seedling trays 3, so that the top of the seedling trays 3 already stacked on the stacking tray 6 is always parallel to the guide surface of the guide device.

[0034] In this embodiment, the seeder body is an existing seeder, such as the Changchun Zhongfa 2BZP-800 rice seedling tray seeder. This seeder can perform operations such as sowing and watering. The specific structure of the seeder will not be described here.

[0035] In this embodiment, the palletizing box 7 is made of stainless steel, and the palletizing tray 6 is made of PVC material, which has high hardness, can support the seedling tray 3, and has low cost.

[0036] In this embodiment, initially, the guide surface of the guiding device, the conveying surface of the conveying part, and the top surface of the stacking tray 6 are parallel, facilitating the transportation and stacking of the seedling trays 3. Then, when the seedling trays 3 begin to be stacked on the stacking tray 6, the telescopic device can extend or retract a corresponding distance according to the number of seedling trays 3 on the stacking tray 6, so that the top of the topmost seedling tray 3 on the stacking tray 6 is parallel to the guide surface of the guiding device and the conveying surface of the conveying part, facilitating the stacking of the next seedling tray 3.

[0037] In this embodiment, the palletizing box 7 can hold 20 seedling trays 3 at a time.

[0038] The seedling tray 3 completes a series of actions such as spreading soil and sowing seeds on the conveying section. One end of the conveying section is first connected to the guiding device and then to the stacking box 7. The guiding surface of the guiding device, the conveying surface of the conveying section, and the top surface of the stacking tray 6 are initially in a parallel state. That is, the seedling tray 3 can enter the guiding device first under the pushing action of the conveying section. The subsequent seedling trays 3 can push the seedling trays 3 that have entered the guiding device, so that the seedling trays 3 on the guiding tray come into contact with the stacking tray 6 in the stacking box 7 and gradually slide onto the stacking tray 6 and be supported by the stacking tray 6. The stacking process continues until a stacking box 7 is filled with stacked seedling trays 3. During this process, the stacking tray 6, supporting the seedling trays 3, uses a telescopic device that adapts to the number of seedling trays 3 by extending or retracting the corresponding height. Specifically, the extension height is the number of seedling trays 3 multiplied by the height of each tray. This ensures that the top of each new seedling tray 3 on the stacking tray 6 is parallel to the guide surface of the guide device and the conveying surface of the conveying unit, facilitating support for the next seedling tray 3 to be stacked on the stacking tray 6. In this way, all the seedling trays 3 can overlap within the stacking tray 6 and the stacking box 7. Once the required number of seedling trays 3 are stacked in a stacking box 7, the user can remove the entire stacked row of seedling trays 3 from the opening in the stacking box 7. This reduces the difficulty of stacking pre-sown seedling trays 3, simplifies the stacking operation, and increases user comfort.

[0039] In this embodiment, the palletizing tray 6 is detachably connected to the telescopic device, which is a telescopic rod 8. An elastic device is provided inside the telescopic device. The palletizing box 7 is provided with an opening for taking out the already stacked seedling trays 3. The opening is located on the side of the palletizing box 7 away from the guide device.

[0040] In this embodiment, the telescopic rod 8 is also made of stainless steel.

[0041] In this embodiment, the telescopic rod 8 is extended and retracted by an elastic device. The telescopic rod 8 includes a mother rod 802 and a daughter rod 801 sleeved in the mother rod 802. The telescopic device is a telescopic spring 803, and the two ends of the telescopic spring 803 are respectively connected to the top of the daughter rod 801 and the bottom of the mother rod 802.

[0042] In this embodiment, the main rod 802 of the telescopic rod 8 is connected to the bottom of the palletizing box 7 by welding.

[0043] The seedling trays 3 that need to be stacked enter the stacking box 7 from the guide device and move out from the opening. The opening is located on the side away from the guide device. This arrangement makes the movement of the seedling trays 3 reasonable, and the operation process of stacking and taking out the stacked seedling trays 3 is relatively smooth and undisturbed.

[0044] The detachable connection between the palletizing tray 6 and the telescopic device allows the entire box of seedling trays 3 to be removed along with the palletizing tray 6 after a box of seedling trays 3 has been stacked in the palletizing box 7. Then, a new palletizing tray 6 can be installed to start stacking a new box of seedling trays 3, which can improve the efficiency of stacking seedling trays 3.

[0045] The elastic device allows the telescopic rod 8 to automatically return to its original position when the stacked seedling trays 3 are removed, facilitating the installation of new stacking trays 6 and making it more convenient to use. In other embodiments, multiple telescopic rods 8 can be designed, for example, four telescopic rods 8 to support the four corners of the stacking tray 6, which provides greater stability.

[0046] In this embodiment, the top of the telescopic rod 8 is provided with a first insert 8011, and the bottom of the pallet 6 is provided with a first slot 602 that cooperates with the first insert 8011.

[0047] In this embodiment, the first insert 8011 and the sub-rod 801 are fixedly connected by welding, the first slot 602 is integrally formed with the pallet 6, and the height of the first insert 8011 is 1.5cm, which can ensure a relatively stable connection effect.

[0048] In this embodiment, the diameter of the insert is 7 cm. In other embodiments, to further increase the stability of the connection between the first insert 8011 and the first slot 602, an adhesive rubber pad can be provided in the first slot 602 to increase the friction between the first insert 8011 and the first slot 602.

[0049] The design of the first insert block 8011 and the first slot 602 simplifies the connection between the palletizing tray 6 and the telescopic rod 8, and improves the efficiency of the connection between the palletizing tray 6 and the telescopic rod 8.

[0050] In this embodiment, the conveying unit includes a conveyor belt 1, with first baffles 2 at both ends of the conveyor belt 1. One end of the guiding device is connected to the first baffle 2, so that the guiding device contacts the end of the conveyor belt 1, and the other end of the guiding device is connected to the palletizing box 7.

[0051] In this embodiment, the conveyor belt 1 is transmitted through the conveyor roller, and two side supports are provided at both ends of the conveyor roller. The first baffle 2 is connected to the side supports by welding.

[0052] In this embodiment, the end of the guide device connected to the first baffle 2 is connected by a second insert and a second slot. The second insert is located at the end of the guide device near the first baffle 2. The second slot is integrally formed with the first baffle 2. After the second insert is inserted into the second slot, it is connected by a first connecting bolt. The first connecting bolt passes through the first baffle 2, the second insert, and the second baffle 401 in sequence to connect the guide rail 4 and the first baffle 2.

[0053] In this embodiment, the guide device is provided with a connecting block 402, and the connecting block 402 is connected to the palletizing box 7 by a second connecting bolt. The second connecting bolt passes through the connecting block 402 and is connected to the side wall of the palletizing box 7.

[0054] One end of the guiding device is connected to the first baffle 2, and the other end is connected to the stacking box 7, allowing the guiding device to connect with the conveyor belt 1 without affecting the use of the conveyor belt 1. At the same time, it makes the conveying surface of the conveyor belt 1, the guiding surface of the guiding device, and the top surface of the stacking device or the top surface of the stacking tray 6 parallel, which facilitates the stacking of the seedling trays 3 that have been sown, and improves the stability of the seedling trays 3 running on the guiding device and the stacking box 7 or the already stacked seedling trays 3.

[0055] In this embodiment, the guiding device includes two guide rails 4, and a second baffle 401 is provided on the top of the two guide rails 4. Two symmetrical third baffles 601 are provided on the pallet 6. The third baffles 601 are located in the extension direction of the second baffles 401. A limiting groove for limiting the seedling tray 3 is formed between the two second baffles 401 and the third baffles 601.

[0056] In this embodiment, the two guide rails 4 are integrally formed with the connecting block 402 by welding on the side away from each other.

[0057] In this embodiment, the second baffle 401 and the third baffle 601 are welded to the guide rail 4 and the pallet 6, respectively.

[0058] In this embodiment, the connecting block 402 is connected to the side wall of the palletizing box 7 by a second connecting bolt.

[0059] In this embodiment, support legs 9 are welded to the bottom of the two guide rails 4.

[0060] The design of guide rail 4 simplifies the structure of the guide device, reduces the amount of material used, and thus lowers the cost of setting up and using the guide device.

[0061] The setting of the first baffle 2, the second baffle 401, the third baffle 601, and the setting of the limiting groove can limit the seedling tray 3 during transportation, making the seedling tray 3 more stable during transportation and stacking, improving the stability of the device during use, and thus improving the effect of transporting and stacking the seedling tray 3.

[0062] In this embodiment, a plurality of rollers 5 are provided on the guide rail 4. The rollers 5 are disposed between two guide rails 4, and the top of the rollers 5 is flush with the guide surface of the guide rail 4.

[0063] In this embodiment, each roller 5 is rotatably connected to a connecting shaft, and the two ends of the connecting shaft are welded to two guide rails 4 respectively.

[0064] In this embodiment, there are 5 rollers 5.

[0065] In this embodiment, roller 5 is also made of stainless steel.

[0066] The roller 5 improves the smoothness of the seedling tray 3's transport on the guide rail 4, and enhances the user's comfort when stacking the seedling tray 3 using this device.

[0067] In this embodiment, the palletizing box 7 has a U-shaped structure. The palletizing box 7 includes a base plate and two side plates vertically arranged on the base plate. The two side plates are symmetrically arranged and arranged on the extension line of the guide device.

[0068] In this embodiment, the two side plates and the bottom plate are integrally formed by welding.

[0069] The U-shaped palletizing box 7 facilitates the stacking of seedling trays 3 and the removal and transportation of the stacked seedling trays 3. It also reduces the number of side walls of the palletizing box 7, reduces material usage, and lowers costs.

[0070] The specific method of using this utility model is as follows: Reference Figs. 1-2When using this device, the first baffle 2, guide rail 4, and stacking box 7 are first connected by the first connecting bolt and the second connecting bolt. Then, the first slot 602 on the stacking tray 6 and the first insert 8011 on the telescopic rod 8 are connected by plugging. After all are installed, the seeder is started. The seeder starts to sow the seedling trays 3 according to the working process. After sowing, the seedling trays 3 come into contact with the guide rail 4 via the conveyor belt 1. Under the pushing action of the subsequent seedling trays 3, the preceding seedling trays 3 are pushed from the guide rail 4 into the stacking box 7 via the roller 5 and supported by the stacking tray 6. At this time, the stacking tray 6 on the telescopic rod 8 bears the weight of a seedling tray 3. The telescopic rod 8 retracts the height of a seedling tray 3 so that the top surface of the seedling tray 3 coincides with the top surface of the guide rail 4. The next seedling tray 3 is directly superimposed on the top of the previous seedling tray 3 in the above process until a box of 20 seedling trays 3 with seeds is stacked.

[0071] At this point, the user lifts 20 seedling trays 3 by hand or with a forklift through the gap between the bottom plate of the stacking box 7 and the stacking tray 6. Then, the telescopic rod 8 returns to its original position under the action of the telescopic spring 803. At this point, the user can install a new stacking tray 6 according to the above process and carry out a new round of stacking. Since the speed of the seeder is adjustable, the sowing process of a seedling tray 3 has many steps, so there is enough time to insert a new stacking tray 6 after stacking a box of seedling trays 3.

[0072] The above description of the disclosed embodiments enables those skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
